| total | 2 days, 2:12:16 | 2 days, 1:16:17 | -1.9% | -1.9% |
Time spent on the 20005 models both runs have. The last column counts only the 19975 that reached the same phase in both: a model that fails earlier stops paying for the phases it no longer reaches.

- The baseline is the newest run of master, not the commit the pull request is based on, so a difference can also come from something merged into master since the pull request was branched.
